Description
Technical field
The present invention relates to the hydraulic pressure moulding process of metal material moulding technology, more particularly, to fabric dyeing machine large radius cylinder.
Background technology
It is pressed into the product of various moulding by the metal light wall pipe such as rustless steel, copper, aluminum, mainly adopt rubber swelling technology, that is,
Metal light wall pipe is placed in the mould of various moulding, then injects liquid rubber in pipe, using pressure produced by rubber swelling
To extrude light wall pipe molding, but rubber swelling technique has that dilating rate is too low, only more than ten percent, product-forming list
Leveling is light.Adopted the water filling swollen type technology of pressurization later, and in light wall pipe, injected water and increase hydraulic pressure, to increase the pressure of extruding light wall pipe
Power, hydraulic stress is evenly distributed, and is not concentrated in specific part, reduces workpiece weld seam, but also there is metal tube and easily occur back
Bullet, the incomplete shortcoming of deformation of transition region.
Content of the invention
The present invention is directed to metal tube in prior art and resilience easily occurs, and the incomplete shortcoming of deformation of transition region, for understanding
Certainly above-mentioned technical problem, the present invention is addressed by following technical proposals:
The hydraulic pressure moulding process of fabric dyeing machine large radius cylinder, this technique comprises the following steps:
Step 1: board making is become the barrel-shaped blank of one end open；
Step 2: blank is placed in a mold；
Step 3: water is injected by the opening of blank to the inside of blank, the bulging that pressurizes is carried out by water to blank；
Step 4: after the pressure stability in blank, be re-filled with water and pressurizeed further, until blank is formed according to mould
Expander；
Step 5: the water blood pressure lowering internal to expansion simultaneously releases water；
Step 6: the expander after shaped by fluid pressure is removed from the molds；
Step 7: expander is polished polish, obtains the large radius cylinder for fabric dyeing machine.
Carry out multisection type pressurization by gradually stepping up pressure, make the fillet of transition region be completely superposed mould, reduce in hydraulic pressure
Blank molding in moulding process not exclusively, easily there is the shortcoming of resilience after molding, meanwhile, prevent excessive leading to of disposably pressurizeing
Blank damage.
Preferably, when carrying out step 4, the pressure stability within blank is between 200mpa-800mpa, then increases
The pressure of 50mpa-100mpa carries out secondary pressurized.The pressure stability keeping blank interior for a period of time plays surely to the deformation of blank
Fixed effect, can prevent blank resilience.
Preferably, when carrying out step 4, the pressure within blank keep 10min-15min stable after, reduce base
The pressure of the internal 20%-50% of material simultaneously keeps 5min-10min, then increases pressure value when pressure makes it restore to stable.Logical
Cross reciprocal increase and blood pressure lowering, make the blank after molding more preferably stable, effectively prevent blank resilience.
Preferably, during pressure remained steady, mould drives the water in blank to rotate and produce centrifugal force, water
By centrifugal force, blank is pressurizeed.By rotation, make water produce outside centrifugal force to blank, promote blank laminating mould
Tool.
Preferably, mold outer surface is provided with gear ring, gear ring is combined with gear, gear drives rotation by motor
Turn.Rational in infrastructure, realize mold high speed and rotate and produce powerful centrifugal force.
Preferably, also including the water injection pipe to water filling in blank, water injection pipe stretches in blank, and water injection pipe is provided with hole.
Multi-faceted water filling can be carried out to blank inwall by hole, strengthen the effect of hydraulic pressure molding, save the time of hydraulic pressure molding.
The present invention, due to employing above technical scheme, has significant technique effect: carry out by gradually stepping up pressure
Multisection type pressurizes, and makes the fillet of transition region be completely superposed mould, it is to avoid the blank molding in hydraulic pressure moulding process is incomplete, one-tenth
The shortcoming that resilience easily occurs after type, meanwhile, prevents the excessive blank leading to damage of disposably pressurizeing.
Brief description
Fig. 1 is the structural representation of the present invention.
The toponym that in accompanying drawing, each number designation is referred to is as follows: 1 blank, 2 moulds, 3 gear rings, 4 teeth
